Colibri is a very versatile survey meter. It features excellent ergonomics such as easy handling, visual and audible alarms and an internal vibrator. The large integrated TFT LCD touch screen is well lit for use both indoors and outdoors, even in bright conditions. Colibri TTC integrates a GM detector processed by a Time To Count (TTC) algorithm. This algorithm extends the detection range of the GM up to 1000 rem/h, thus enabling measurements even in critical situations. For measurements, the Colibri displays both the internal GM dose rate in fast reacting semi-log bargraph and an averaged digital reading. Colibri simultaneously displays the dose rate and the integrated dose. When an external probe is connected, it displays the external probe measurement and the dose rate from the internal detector.
